There is a built-in extension mechanism toįHIR modeling uses a composition approach. Structure for the core information set that is shared by most implementations. FHIR resources aim to define the information contents and The philosophy behind FHIR is to build a base set of resources that,Įither by themselves or when combined, satisfy the majority of common

Resources all share the following set of characteristics: All exchangeable content is defined as a resource. The basic building block in FHIR is a Resource. Without requiring the implementer to have intimate knowledge of the RIM or any HL7 v3 derivations. This ensures alignment to HL7's previously defined patterns and best practices Implement, and rigorous mechanism for exchanging data between healthcare applications.įHIR has built-in mechanisms for traceability to the HL7 RIM and other important content Leverages existing logical and theoretical models to provide a consistent, easy to (See Comparing FHIR to other HL7 standards)įHIR aims to simplify implementation without sacrificing information integrity. FHIR can be used as a stand-alone dataĮxchange standard, but can and will also be used in partnership with existing widely Implementing HL7 v2, HL7 v3 and the RIM, and CDA. Of lessons around requirements, successes and challenges gained through defining and Is a new specification based on emerging industry approaches, but informed by years Healthcare data exchange and information modeling standards for over 20 years. HL7 has been addressing these challenges by producing (See Coming digital challenges in healthcare) Machine-based processing, the data must also be structured and standardized.

This page provides an overview of the standard, and serves as a road map for first-time readers of the specification to help find your way around FHIR quickly. Welcome to the FHIR (Fast Healthcare Interoperability Resources) Specification, which is a standard for exchanging healthcare information electronically.
